a commonly used mathematical model for electrical and computer systems
circuit model
the elements that comprise the circuit model
ideal circuit components
based on mathematical techniques and is used to predict the behavior of the circuit model and its ideal circuit components
circuit analysis
the actual electrical system, constructed from actual electrical components
physical prototype
the energy per unit charge created by the separation
the rate of charge flow
electric current
points of connection to other circuiet components
has only 2 terminals, described mathematically, cannot be subdivided into other elements
ideal basic circuit element
whenever the reference directions for the current in an element is in the direction of the reference voltage drop across the element, use a positive sign in any expression that relates the voltage to the current
passive sign convention
the product of the current in the element and the voltage across the element
a device that is capable of converting nonelectric energy to electric energy and vice versa
electrical source
a circuit element that maintains a prescribed voltage across its terminals regardless of the current flowing in those terminals
ideal voltage source
a circuit element that maintains a prescribed current through its terminals regardless of the voltage across those terminals
ideal crrent source
establishes a coltage or current in a circuit without reling on voltages or currents elsewhere in the circuit
independent source
establishes a voltage or current whose value depends on the value of a voltage or current elsewhere in the circuit
dependent source
models a device capable of generating electric energy
active element
models physical devices that cannot generate electric energy
passive elements
the capacity of materials to impede the flow of current or the flow of electric charge
